SMF115zz Bearing Product Overview & Core Advantages
The SMF115zz is a metric miniature ball bearing designed for precision applications requiring compact dimensions and reliable performance. Constructed entirely from stainless steel, it offers excellent corrosion resistance. As a single row deep groove ball bearing, it is primarily designed to handle radial loads efficiently. Its key advantages include a compact flange design for secure mounting, shielded construction to protect against contamination, and compliance with ABEC1 precision tolerances, making it suitable for high-speed operation and applications demanding dimensional stability.
SMF115zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SMF115 | Indicates the bearing series and core dimensions: 5mm bore, 11mm outside diameter, 4mm width, with a flange. |
| zz | Denotes that the bearing is shielded on both sides (2Z). This provides protection against solid contaminants while allowing for high-speed operation compared to sealed bearings. |
SMF115zz Bearing Structural Features & Performance Benefits
- Flanged Design & High Rigidity: The integrated flange (OD: 12.6mm) facilitates secure and precise axial location during mounting, simplifying assembly and enhancing operational stability.
- Radial Load Capacity: The deep groove raceway and construction with 8 balls enable efficient handling of radial dynamic loads up to 123 lbf and static loads up to 46 lbf.
- High-Speed Performance: The combination of a stainless steel cage, shielded design, and ABEC1 precision tolerances contributes to a high limiting speed of 40,500 rpm.
- Corrosion Resistance & Longevity: All components, including rings, balls, cage, and shields, are made from stainless steel, offering excellent protection against rust and corrosion in harsh environments.
- Precision Internal Clearance: The specified MC3 radial internal clearance (0.002mm to 0.013mm) ensures smooth, low-noise, and low-vibration operation, which is critical for sensitive applications.
SMF115zz Bearing Typical Application Areas
This bearing is ideally suited for compact, high-speed devices and precision instruments, including:
- Small DC Motors and Stepper Motors
- Precision Gearboxes and Encoders
- Medical and Dental Hand Tools
- Office Automation Equipment (e.g., printers, scanners)
- Radio Control Models and Drones
- Instrumentation and Measurement Devices
